Green Energy Corridors

    

The Green Energy Corridor Project aims at synchronizing electricity produced from renewable sources, such as solar and wind, with conventional power stations in the grid.


For evacuation of large-scale renewable energy, Intra State Transmission System (InSTS) project was sanctioned by the Ministry in 2015-16. It is being implemented by eight renewable-rich states of Tamil Nadu, Rajasthan, Karnataka, Andhra Pradesh, Maharashtra, Gujarat, Himachal Pradesh, and Madhya Pradesh. The project is being implemented in these states by the respective State Transmission Utilities (STUs).

 

The project includes approximately 9400 ckm transmission lines and substations of a total capacity of 19000 MVA to be completed by March 2020. The purpose is to evacuate 20,000 MW of large-scale renewable power and improvement of the grid in the implementing states.

The total project cost is Rs. 10141 crores. The funding mechanism consists of 40% Government of India Grant (total Rs. 4056.67 crores), 20% state equity and 40% loan from KfW, Germany (500 million EUR).

 

The Central grant is disbursed in two installments to the STUs: a) 70% advance on the award of contract, and b) balance 30% after successful commissioning and three months of performance testing.


Institutional Arrangements & Implementation Strategy

 

The project is being implemented by respective State Transmission Utilities (STUs) allocating the work through a competitive bidding process. The Ministry monitors the project every month. A Project Appraisal Committee under the chairmanship of concerned Joint Secretary and with members from CEA & PGCIL monitors the project & recommends on 

the disbursal of the central grant to the STUs.
